We asked superstar rappers from hip-hop’s hottest splinter subgenres to break ‘em down for us.

The insider: Grime, Lady Sovereign, 19. Check out her EP Vertically Challenged and upcoming full-length.

The scene: London’s East End

What’s it sound like: Rapid-fire lyrics about day-to-day life in working-class London over video-game bloop-de-bloop beats

At the top of the game: Dizzee Rascal, the Roll Deep Crew. New music by Missy Elliott and Pitbull reeks of grime influence

Extra special: Lady Sov named her pet hamster Jentina, after a rival rapper- “’cause it made pointless noise.”
